Implemented in changeset 37e4d310b065. For BigTIFF output you need to
compile enblend/vigra with libtiff with BigTIFF support and add
`--parameter=export-bigtiff´ to command line.

Title:
Maximum TIFF file size 4GB
Status in Enblend:
Fix Committed
Bug description:
Hi there!
After running for 2 days the enblend binary that I compiled myself
from the enblend sources revision 1049 failed with this error:
enblend: info: writing final output
enblend: error: Maximum TIFF file size exceeded
enblend: an exception occured
enblend:
Postcondition violation!
exportImage(): Unable to write TIFF data.
(/build/buildd/libvigraimpex-1.9.0+dfsg/src/impex/tiff.cxx:811)
enblend: info: remove invalid output image "x1.tif"
===================================================
I've used these parameters: --compression=LZW --verbose
--output=x1.tif
The output pixel dimensions would have been 119598 * 17362 =
2076460476 which is still well within the 2^31 pixel count limit =
2147483648
In the bug report #685105 I've mentioned that I've run into this problem
before, and back then Jeff Hungerford (hungerf3) told me:
"If you are seeing that error, either the TIFF library you linked against
doesn't support bigTIFF, or for some reason it decided to only use the old
format."
It would be very kind of you if you could guide my way how to compile
enblend (and libtiff?) in a way that enblend will not fail when the
output exceeds 4GB in file size.
Or is there maybe a way to use another output format then tif to
workaround this problem? (With Gimp I like to use png for images that
are too big for 4GB tif, it has the same problem of failing to save
>4GB tiffs for me)
